Xuefu Zhang commented on HIVE-6411:
-----------------------------------
The only thing that's holding this is time: I haven't got a chance to go over
the latest patch yet. One thing that I'm unclear about is the predicate
pushdown related changes, per my previous comments.

One thing that I don't quite get is the changes related to predicate pushdown.
Is this necessary?

An explanation of the nature of the change should help. Otherwise, it may take
more of my time digging around.
> Support more generic way of using composite key for HBaseHandler

> HIVE-2599 introduced using custom object for the row key. But it forces key
> objects to extend HBaseCompositeKey, which is again extension of LazyStruct.
> If user provides proper Object and OI, we can replace internal key and keyOI
> with those.
> Initial implementation is based on factory interface.
> {code}
> public interface HBaseKeyFactory {
> void init(SerDeParameters parameters, Properties properties) throws
> SerDeException;
> ObjectInspector createObjectInspector(TypeInfo type) throws SerDeException;
> LazyObjectBase createObject(ObjectInspector inspector) throws
> SerDeException;
> }
